With the Black Eye Macro G4 for smartphones you can increase a subject up to 15x. You attach this clip to your mobile phone as a clothespin. Here you turn the macro lens. With this lens you have a focusing distance between 20 and 26 millimeters. This allows you to take sharp photos of subjects that are very close. The coating on the lens prevents reflections and image distortions. The universal clamp works with smartphones, tablets, laptops and devices with dual lenses.

Very well constructed product. Comes with a carrying bag, lens cover and lens cloth. You can get very sharp and detailed pictures. If you want fully magnified pictures, you do have to get close to the subject!
